What is Maximizer TM?
Maximizer is a complete memory manager program for your IBMTM or
IBM compatible compatible computer system. Regardless of the
type of computer you have, if your are experiencing memory
problems the odds are that Maximizer has a solution for you.
Maximizer technology works on the concept of utilizing the
unused, and otherwise wasted, memory above the 640K more commonly
known as "Upper Memory Blocks". Maximizer is designed to run as a
software only (no hardware needed) on IBM/AT compatible systems
equipped with an 80386/80386sx/80486 processor chips. These
processors are capable of virtual memory techniques which allow
the use of extended memory in the MS-DOS region. Maximizer will
use some of the extended memory to fill the vacant Upper Memory
Blocks and use them. Maximizer can also be used to cache or
shadow your ROMs (i.e. Bios, Video ...etc) and control the
allocation of XMS memory for your programs. Maximizer also works
as software only on IBM/AT compatible systems equipped with the
Neat 286 or Neat 386 ChipSet from Chips & Technology Corp.
Maximizer will use the shadow RAM feature of the Neat ChipSet to
add Upper Memory Blocks to the MS-DOS. If your computer system is
not one of the above (i.e. 8088 or 80286 without Neat ChipSet)
the you must use either the Max-8 or Max-16 Memory Adapters, with
their own memory on board, to provide Upper Memory Blocks for
your system.
How It Works
The MS-DOS operating system is based on the 8086/8088 processors
which can address a maximum of one mega bytes of system memory
organized as sixteen Segments of 64K bytes each (see figure 1).

Figure 1 - MSDOS System Memory Map
Maximizer can increase the available MS-DOS Program Memory by
utilizing locations reserved for the optional video display
systems. For example, if your video display is a Monochrome or
Hercules, there is an unused 64K memory block in the video
memory area which can be added to the MS-DOS Program Memory
giving your system an additional 64K bytes. A computer system
with a CGA video adapter can use Maximizer to increase the MS-DOS
Program Memory by 96K for a total of 736K bytes. Figure 2 shows
how a typical computer can use available video memory to increase
MS-DOS Program Memory.

Figure 2 - How Maximizer Works
Maximizer can also save precious MS-DOS Program Memory by using
the memory locations reserved for System ROM Expansion. If
unused, this Upper Memory region can form additional blocks of
memory of up to 256K Bytes. Although these Upper Memory Blocks
are non-contiguous to the MS-DOS Program Memory, they can be
used to load TSR programs, Device Drivers and Disk Buffers,
which normally reside below 640K (see Figure 2). Maximizer can
utilize memory blocks as small as 4K bytes and therefore can
share a segment with others that may be using only a part of the
segment. For example, a typical ArcNet network adapter card
uses 200 bytes beginning at address D000. Maximizer can utilize
the balance of Segment D starting at next 4K address which is
D100. Unlike Expanded (EMS) or Extended memory, Maximizer uses
the Conventional memory locations of MS-DOS that are "Vacant" and
are usable by virtually any program. Maximizer can even be used
in conjunction with Expanded or Extended memory. Some
applications (i.e. FoxBase+, MenuWorks Advanced, PC-Xview) can
also recognize and use the Upper Memory Blocks within their
application. Maximizer has been tested with many Network
operating systems including: Novell, 3-Com, ViaNet, Banyan,
TOPS, PowerLAN, Network-OS, 10Net and AT&T StarLAN.
System Requirement
Maximizer works as software only with all IBM/AT compatible
systems with 80386/80386sx/80486 processors or 80286 computers
using the Neat ChipSet from Chips & Technology Corp. If your
computer system is not one of the above (i.e. 8088 or 80286
without Neat ChipSet) then you must use either the Max-8 or
Max-16 Memory Adapters with their own memory on board to provide
Conventional and Upper Memory. Maximizer software requires MS-DOS
3.1 or higher.
Memory Requirement
If Maximizer is being used as a software only then you must have
at least 384K bytes of extended memory. With the Neat ChipSet
Maximizer will use the Shadow RAM area between 640K and 1 Meg (no
extended memory needed).
Warning:
On the Neat 286 and Neat 386sx computers equipped with one Mega
byte of main memory, the 384K of shadow RAM can be relocated and
used as Expanded or Extended memory. Maximizer program will reset
the relocation bit which disables your Expanded or Extended
memory feature. You must reset this bit in the CMOS memory also.
If you computer uses the Neat 386 or if you have more than one
Mega byte of main memory this problem does not affect your
environment.
Technical Support
SoftNet offers free technical support to registered users of
Maximizer Memory Manager. Before contacting our technical
personnel please take the time to read this manual. This may
save you and us a considerable amount of time. If you have to
contact us it would be advisable to have access to the computer
in question during your call. You may call or Fax your

INSTALLATION
Maximizer software is automatically installed on your computer
using the INSTALL.EXE program supplied on the distribution disk.
This program will display the copyright notice and ask for your
name and the destination path. Your name will be embedded in the
MAXIMIZE.COM program as the registered owner of this program. To
invoke INSTALL place the distribution disk in a floppy drive.
Logon to that drive and type install:
A:\>INSTALL <CR>
